FIELD: automobile transport. SUBSTANCE: invention relates to any electric vehicles (car, trolleybus, street car, electric train, etc) operating with frequent accelerations and braking, Recuperation of kinetic energy is performed by conversion of vehicle braking kinetic energy, for instance car with electric transmission, into electric energy which is subsequently accumulated in hydraulic motor recuperator providing conversion of kinetic energy of rotation of high-speed rotor of hydraulic motor into electric energy and vice versa. Recuperation of kinetic energy by hydraulic motor is carried out in three steps. At first step high speed rotor of hydraulic motor is set into rotation by external electric source to obtain reference speed with stabilization of reference speed of high-speed rotor, and at second step of recuperation car braking kinetic energy is converted into kinetic energy of high-speed rotor of hydraulic motor owing to the fact that high- speed rotor is additionally brought to rotation at working speed exceeding reference speed by source of power obtained at car braking. At third step hydraulic motor recuperator is changed over for operation as generator and its energy is converted into electric energy and is directed to provide acceleration of car simultaneously reducing speed of high-speed rotor and its kinetic energy to reference speed and directing liberated energy to provide acceleration of car. According to first version, realization of proposed method of energy recuperation is carried out on car furnished with internal combustion engine with electric generator and electric transmission with motors-in-wheels which is furnished additionally with two-rotor hydraulic motor asynchronous energy recuperator. Second version of vehicle with energy recuperator is implemented on trolleybus including contact system, and traction electric motor with electric transmission. Trolleybus is furnished additionally with two-rotor asynchronous hydraulic motor energy recuperator. Third version of vehicle with energy recuperator is implemented on car furnished with internal combustion engine with electric generator and electric transmission with motors-in-wheels, car being with asynchronous hydraulic motor energy recuperator. Proposed invention makes it possible to solve problem of energy recuperation at braking and starting from rest. Moreover, use of hydraulic motor recuperator provides 3-4 times reduction of installed power of internal combustion engine and electric generator by compensating for deficient impulse power by energy of hydraulic motor recuperator. EFFECT: two-fold reduction of fuel consumption under city traffic conditions. 5 cl, 10 dwg, 1 tbl
